Yes, good idea.  But only if we have access to the cache
locations that we have to flush. These would be the "remote-path"
properties of every Tramp connection, and I _think_ there's
an accessor for that, but I have to check.

Which reminds me, that patch I sent has a big thinko :-)

If you re-set tramp-remote-path you get flushing for the
next call to tramp-get-remote-path, which will be for a given
connection.  At that moment you forget changes by setting
tramp-last-used-remote-path so and you will fail to flush for
the next connection.

Not hard to fix, we just have to make sure to flush _all_
connections when we detect the change, however we detect it.

João
